# Overview As a disclaimer, this is my first PR to LLVM and while I've tried to ensure I've followed the LLVM and libc++ contributing guidelines, there's probably a good chance I missed something. If I have, just let me know and I'll try to correct it as soon as I can. This PR implements `std::ranges::iota` and `std::ranges::out_value_result` outlined in [P2440r1](https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2021/p2440r1.html). As outlined in the paper above, I've: - Implemented `out_value_result` and added to `<algorithm>` - Added `out_value_result`, `iota_result`, and two overloads of `iota` to `std::ranges` in `<numeric>` - Updated the version macro `__cpp_lib_ranges_iota` in `<version>` I've also added tests for `ranges::iota` and `ranges::out_value_result`. Lastly, I added those structs to the appropriate module files. Partially implements #105184 EDIT: Forgot to mention in the original post, thanks to @hawkinsw for taking a look at a preliminary version of this PR! # TODOs - [x] Updating the range [status doc](https://github.com/jamesETsmith/llvm-project/blob/main/libcxx/docs/Status/RangesMajorFeatures.csv) - [x] Ensure all comments from https://reviews.llvm.org/D121436 are addressed here - [X] EDIT (I'll do this in a separate PR). ~~I'm open to implementing the rest of P2440r1 (`ranges::shift_left` and `ranges::shift_right`) if that's ok, I just wanted to get feedback on `ranges::iota` first~~ - [x] I've been having trouble building the modules locally and want to make sure that's working properly Closes: #134060
